On the base of aerothermodynamic equations of the viscous fluid flow expressed by the non-orthogonal coordinate system and its' components the boundary layer equations of S1 stream surface can be obtained by "Mass-Weighted-Averaging" and the boundary layer approximating procedures. The subject of this title is published by two parts. The first one is concerned with only the cascade problems of the low speed and the second one will consider the effects of the compressibility of the gases. Two forms of the stream...

On the base of aerothermodynamic equations of the viscous fluid flow expressed by the non-orthogonal coordinate system and its' components the boundary layer equations of S1 stream surface can be obtained by "Mass-Weighted-Averaging" and the boundary layer approximating procedures. The subject of this title is published by two parts. The first one is concerned with only the cascade problems of the low speed and the second one will consider the effects of the compressibility of the gases. Two forms of the stream function equation are discussed in present paper and their accuracies of the solutions are very closed. The sample calculations have shown that the effect of the stream surface thickness must be taken into account in the quasi-three-dimensional blade stream surface boundary layer calculations. The comparison of computation with experiments indicated that present method and computer program are reasonable and suitable for the use in practice.

The large angular separations and the rare appearance of the third images have been puzzles for seven gravitationally lensed quasars (GLQs) found, so far [1], In this paper, the relation between GLQs and their angular separations is statistically calculated using King galaxies as deflectors and all QSOs in A New Optical Catalog of QSOs [14] as sources. A great number of numerical calculations show that(a) The model can produce the same distribution of GLQs with their separations as the observed curveA large angular separation would occur due to the core of galaxy.(b) The third image is much fainter than the primary one. For △mac.<2, only two images appear. It is consistent with the observation.(c) In order to fit the distribution (1), galaxies must satisfy the following requirements:where Mu is the upper mass limit, M/L the mass-to-light ratio, R the radius, and a the core radius.It has been shown that not only the observations of GLQs can be explained perfectly in the model, but the gravitational lens effect can also be used as a tool to detect the structures of galaxies.

本文以King模型去描述星系的引力透镜行为,把已知类星体作为光源,从统计上计算了引力透镜类星体对与其像间分离的关系。结果表明,星系的透镜行为不仅能解释全部透镜事例,而且可以揭示出星系的某些统计参数,如星系的最大质量、平均半径、平均核半径及质光比。宇宙中星系质量密度因子,Ω_g,亦可从中求得。
